D4 DUBS 0 Posted December 20, 2009 Report Share Posted December 20, 2009 Hi guys,Need your advice, I have just supercharged my car, but lent my mate my ECU to start his own car, the thing is, a few weeks later I put the ECU back in my motor and the car turns over but wont fire.Any ideas what could be the issue. The VR6 is an OBD1. The car was working perfectly fine before I charged it and also whilst it was running the charger so now confuesed what may have happened.Any help would be appreciated, what to look at etc....I have a new battery in the car, so this is working fine.Car has a Toad Ai606 in there also.Thanks in advance.

legvw 0 Posted December 27, 2009 Report Share Posted December 27, 2009 Have you had any luck with your car yet mate? If you've replaced the battery, and had the ecu out it could have locked the ecu? Have you tryed plugging into vagcom to see if it can read your ecu? Link to post Share on other sites

bpm 0 Posted February 25, 2010 Report Share Posted February 25, 2010 There's a fuel pump relay in the fuse board (can't remember which one off hand) and also when I first transplanted my obd1 vr6 into the mk2, the ecu wasn't getting a proper ground, stopping the car starting.You also might check the ignition switch too, it might not be providing power to the fuel pump relay.
